Hi guys, first post on this discussion forum ever. Nice to meet you all. Hope this belongs here.
I have just returned to college for IT after a lapse in enrollment. We're going to be working with Linux more in the future, and even the Powershell in Windows too. I have been messing around with the Raspberry Pi I got for one of my classes, but I pretty much have to Google every command I use in the terminal for it since I'm not that familiar with Debian (sorry, Raspbian), the Powershell, or Linux terminals at all.
My question is this: what are some essential, need to know commands for moving around in and using the Powershell? You can give me one or several, list form, add a short description of what it does, whatever. I'll be jotting them all down in my notes with some extra fluff anyways for future reference.
Appreciate it guys, thanks.
TL;DR: Need useful, necessary Powershell / Linux terminal commands.
Find a nice book/primer on Unix commands. They mostly work on Linux as well. You need 'cd' to move between folders, 'ls to list files, type to display text files, 'whereis' to find the location of a file 'su' to switch to root access. most commands will list command line options if you add the --help option. Conversely, you can try 'man '+ command to get help on most commands.
When I was working a lot on Linux/Unix, I found a book called "Tricks of the Un ix Masters". It helped immenselywith file editing and bash scripts.
Good Luck and Dive In,
I'm building a linux-based bluetooth speaker that uses speech recognition to display captions for what is playing on the speaker and I'm trying to figure out where to start in terms of where to intercept the bluetooth audio. I understand that ALSA and PulseAudio could be used to intercept audio from applications before they get sent to the audio hardware, but I haven't had much luck figuring out how a bluetooth source can be intercepted. Any help understanding how bluetooth fits into the audio architecture would be appreciated. Here's what I'm trying to do:
Phone->bluetooth->my custom linux-based bluetooth speaker->run raw audio through speech AI->audio out to speakers and captions out to display.
am I looking for someone who specializes in hardware programming? I have a sound card which is at the same time control surface is the digi 003 console of digidesign. at the time this card was dedicated and only worked with a specific software, protools 7, but as the company was acquired they stopped the software updates and now the control part is unusable, we only have access to the card are and at 2out of 8. suddenly I was wondering if it was possible to reprogram it, it isin firewire. if it was possible to go into it somehow and unlock it?
suddenly on my 2008 macpro I installed the famous linux studio that you helped me to troubleshoot, thank you again but it's been a while since I wonder if I could not hack my card to be able to use it at 100 %
You might be able to use nmap to find out. You can use the -Pn option to tell nmap to skip the ping scan to determine if the host is up. Be aware that nmap will try to connect to a wide range of known ports, which might trigger watchdogs on the target network. In general, using nmap on networks that you are not a valid user of is considered bad manners, so discuss with the network owner before using.
Your success will depend on how the firewall is configured. If it is set up to block all access from WAN for that host (e.g. drop all inbound/outbound packets to/from the host you are interested in), you will never get any response from the host. Your only hope may be that you can access a different host on the target network and be able to try to ping or connect to the host from there.
My current OS gparted obviously does not see md device associated with the array, but it sees the USB /dev/sdx (and all the partitions) , and it does not exist in mdadm.conf file. Also mdadm --detail --scan --verbose cannot see it either - no surprise here.
Is there a SAFE way to recreate RAID5 md device in my current OS?
Can I use mdadm --create ..... to keep current data intact?
